dry-mix concrete 中文意思是什麼
dry-mix concrete
解釋
干拌混凝土-
We research the causes of concrete cracking, develop the high performance anti - cracking additive, optimize the concrete mix and construction techniques, increase the stability of concrete volume by shrinkage compensation, enhance splitting tensile strength, and can meet demand of high workability of fresh concrete. in the study, a thorough investigation of this problem is made from all points of view, with the aid of various modern measurement & testing technology and different theories & methods in surface physical chemistry, structural chemistry, solid - state chemistry, composite materials, fracture mechanics, etc. our research results have shown that the various shrinkage of concrete cause concrete cracking in building engineering, such as autogenous shrinkage, dry shrinkage, temperature shrinkage, plastic shrinkage, carbonized shrinkage, etc
目前，解決混凝土開裂的方法是綜合的，我們調查研究了混凝土開裂的原因，開發研製了高性能抗裂外加劑，優化混凝土的設計和施工方法，並通過補償收縮達到混凝土體積穩定，提高抗裂強度，滿足混凝土拌和物高工作性能的要求。本研究採用多種測試技術，應用表面物理化學、結構化學、固體化學、復合材料學、斷裂力學等多學科的理論與方法，從不同的角度進行深入的研究和探討。通過調查研究建築工程中出現的混凝土開裂、滲漏問題，發現混凝土在非荷載作用下開裂主要是由混凝土的自收縮、乾燥收縮、溫度收縮、塑性收縮、碳化收縮等各種收縮變形引起的。 -
Self - compacting light aggregate high performance concrete ( abbreviated sclc ) is a new type of hpc with the dry apparent density of less than 1950 kg / m3, which can be made by replacing ordinary aggregete with light aggregate and adopting a new design of concrete mix on the basis of ordinary self - compacting concrete
自密實輕骨料高性能混凝土（ sclc ）是在普通自密實混凝土的基礎上，用輕骨料代替普通骨料，採用一定配合比技術配製而成的一種干表觀密度小於1950kg m ~ 3的新型高性能混凝土。
